Hello! I somewhat inherited a Case 580c, and I have been repairing it this summer. I have replaced the seals on a stabilizer, tilt, and both swing cylinders. I also replaced the brake slave units.
I was using the backhoe when I realized the steering was unresponsive and worsening, I stepped downward and saw hydraulic fluid spraying from a steering cylinder!
I have removed both rods, however, I cannot unthread the pistons from the rods. I used rubber and vise grips to try and remove a piston, but it would not budge—I marred the piston a little. Should I use a fine sandpaper to smooth a high spot on the piston? Could I do the same for a high spot on the rod?
I think I will heat the threaded rod that the piston threads onto and be careful not to melt the aluminum piston.
Can you help me remove the pistons from the rods? I appreciate your consideration and any advice.
Thank you,
John
